LABELING-MACHINE.

Specification of Letters Patent.

Patented Feb. 25, 1919.

Application filed August 31, 1918. Serial No. 252,234.

To all whom it may concern Be it known that I, ADoLr POLLATSEK, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and'State of New York, have invented a new and Improved Labeling-Machine, of which the following is a full, clear, and exact description.

This invention relates 'to a labeling machine and has for an object the provision'of an improved construction which is semi.- automatic and which will apply and press labels on bottles, cans and the like of different sizes and shapes.

Another object of the invention is to pro- I vide an arrangement of label applying mechanism which will apply labels automatically to bottles manually fed into the machine and manually removed.

A still further object of the invention 18 the provision of a machine in which the parts may be adjusted for taking care of different sized bottles and labels applied thereto with equal pressure regardless of the size of'the bottles. 7

In the accompanying drawings:

Figure 1 is a side viewof a labeling machine disclosing an embodiment of the in vention.

Fig. 2 is a longitudinal vertical section through Fig. 1.

Fig. 3 is a transverse sectional view through Fig. 1 on line 3-3, the same being on an enlarged scale.

Referring to the accompanying drawings by numerals 1 indicates a frame provided with brushes and connecting bars for supporting various parts of the machine. Arranged adjacent frame 1 1s an auxillary frame 2 provided with a numberof uprights 3 having ways or grooves therein for receiving the sliding members 4: of the ad ustable frame 5, said adjustable frame 5 having a flexible support 6 for bottle 7. The frame 5 is provided with racks 8 and meshing with pinions 10 and 11, said pinions being rigidly secured to shaft 12 which 1s provided with a hand wheel 13, whereby whenever hand wheel 13 is rotated the racks and also frame 5 will be moved upwardly or downwardly according to the rotation of the hand wheel.

After the frame has been properly adjusted for the particular sized bottle 7 it is allowed to remain stationary, while the respective bottles 7 are placed on the support to properly lay on the bottle when pressed against the same an endless belt 1a is provided which passes over rollers 15, 16, 17 and 18. Each of these rollers is provided with a sprocket wheel adjacent each end, the teeth of which pass through the eyelets 19 and 20 (Fig. 3), whereby the power from the roller 15 will be transmitted to the other rollers and there will be no slipping of the belt. The power roller 15 is connected with the power wheel 21, which power wheel receives power from any suitable source not shown. The roller 17'is partially submerged in a paste container 22 so as to receive paste therefrom and supply it to the outer face or surface of the belt or apron 14 from which the paste is transmitted to the labels 23 as the same are brought into contact therewith. The labels 23 are arranged in a stack on a pivotally mounted support 24 and positioned so that their rear or back face will be next to the belt or apron 1 1. At the proper time the shaft 25 to which the support 24. is rigidly secured is tilted sufficiently for causing one end of the stack of labels 23 to engage the belt whereupon the belt 11 will remove the upper label and pass the same beneath the moistening roller 26. Roller 26 is an idler and carries a covering fabric of any suitable kind which is maintained moist by water from the container 27, which water drips slowly through the discharge nozzle 28. In this way each label receives paste from the belt or apron 1A and water from the idler 26 so as to prevent any curling when applied to the bottle. Some paste may be applied to the idler 26 from time to time, but this is kept in a more or less liquid state and consequently will not injuriously affect the label as it passes therebeneath.

During the operation of the machine the label travels from the idler 26 over the power roller 15 and is removed by the shelves 29 and 30, said shelves preferably having a sharp edge 31 adjacent the belt or apron 14: so as to in a certain sense peel off the label from the apron. As the adhesive which shelves are spaced apart as shown in Fig. 3 for allowing the pressure foot 32 to pass downwardly and move the label against the bottle 7. The pressure foot 32 will press merely the central part of the label against the bottle and the remaining part of the label will be pressed against the bottle byrollers33 and 34 hereinafter fully described. The pressure foot 32 is connectedwith a rack 35 which meshes with pinion 36, said pinion being rigidly secured to shaft 37-, which shaft carries a sprocket Wheel 38 over which the chain 39 passes. Chain 39 also passes over sprocket wheel 40 which sprocket wheel is rigidly secured to shaft 41; In order to provide a proper back and forth rotary movement of the sprocket 40 and the consequent back and forth movement of the parts associated therewith shaft-4E1 is rigidly se cured to lever d2. Auxiliary levers 43 and 44- are also rigidly secured to shaft i1 and may be secured to each other. Lever 44: is pivotally connected at d5 to link 46 which link is rcciprocat'ed by the wheel 47 to which it is pivotally connected by the wrist pin i8. lVheel 47 is rigidly secured to the shaft 49 to which the power roller 15 is secured and also to which the power wheel 21 is secured. Vhen the machine is not resting the wheel 47 is continually rotating and consequently continually moving li'nk i6 back and forth and oscillating lever 44; shaft 41 and asso' ciate parts so as to cause the pressure foot 32 to move up and down, namely from the position shown in Fig. 2 downwardly until it is pressing the label against the bottle 7 and then back to the posit-ion shown in Fig. 2. The size of the sprocket wheels '38 and 40 and the size of the pinion 36 are of proper proportion to provide this movement by the back and forth movement of lever 44 and associate parts. Lever 4:3 is pivotally connected to link 50 which link is pivotally con nected at 51 to arm 52 which arm is rigidly secured to the shaft 25 carrying the support 24 holding the labels 23. By this connection the support is moved toward and from the belt or apron 14 in proper timed relationship to the movement of the pressure foot 32 and associate parts whereby the labels will be properly spaced so that a label will be on the shelves 29 and 30 when the pressure foot moves downwardly therebetween. Lever 42 is pivotally connected to a link 53 which is formed with a slot 54 at the lower end, which slot accommodates the clamping screw 55, which clamping screw passes through a slot 56 in the lever 57-. Lever 57. is rigidly secured to the shaft 58, said shaft carrying an arm 59 also rigidly secured thereto and carrying a connecting link 60-, which is pivotally connected at 61. to arm 59 and pivotally connected at 62 to a lever 63. Lever 63 is pivotally mounted at 64; on the frame 5 and carries an operating link 65 which is pivotally connected with lever 63 at 66 and to the lower end of links 67 and68 at 69; thereby whenever link 65 is raised these links will also be raised and the auxiliary links 67 and 68' will be moved laterally or horizontally. The auxiliary liiiks 67 and 68' are pivotally connected to the levers 70 and 71 respectively said levers being pivotally mounted at 72 and 73 on frame 5. These levers carry arms Tel and 75 which are pivotally connected thereto and which are bent to the shape shown in Fig. 3. These levers are provided with roller rctaining brackets76 and 77 each of said brackets carrying a spring 78 hearing at the center against the bracket and at the ends against the ends of the journal member 79 of the respective rollers and 3%. As shownin Fig. 2 thedepending ends of the respective brackets 7 6 and 77 are slotted so that the square ends of the shaft 79 may slide back and forth therein without rotatin'g, spring 78 normally holding the rollers in an outer position. This shaped end of the bracket 76 is desi'rable in order toprevent the ends of the brackets 76 and 77 from striking the bottle while at the same time allowing a horizontal independent motion of the respective rollers so as to take care of any slight inequalities in the bottle or label asthe case may be. I

In order to cause the rollers to properly engage the label and press the same against the bottle as shown-in F ig. 3 links or piston rods 80 and 81 are pivotally connected to the respective arms 74: and 75, said piston rods carrying steps 82 and 83 at their lower ends, said stops being engaged by the respective springs 84 and 85 surrounding the piston rods/ The upper end or the end op posite the stops S2 and 83 of the respective springs engages the caps 86 and 87 of the cylinders 88 and 89. These cylinders are pivotally mounted at 90 and 9 1 on the auxiliary links G l (and 68'. These springs ordinarily are sufiiciently stiff to prevent any movement of the rods 80 and 81, but in the case of a peculiar shaped bottle said springs will operate for allowing the rollers to pass properly thereover. In addition these springs will allow a yielding action in case a larger bottle is supplied thanthe movable frame 5 is adjusted to accommodate.

lVhenthe parts are in the position shown in Figs. 1 and 2 a label has just been applied, the bottle 7 is removed and a new bottle substituted while the machine continues to rotate. As soon as the label 23 reaches the dotted position indicated on the shelves 29 and 30 the pressure foot '32 will move downwardly and press the same downwardly between the two shelves and against the new bottle 7. v As the pressure foot moves downwardly the rollers 33 and 84 will also move downwardly as indicated in dotted lines in Fig. 3, this downward movement of the rollers being an idle movement. As the pressure foot 32 and associate parts move upwardly rollers 33 and 34: will also move upwardly to the position shown in Fig. 3 and will then move downwardly and on the sec ond movement will engage the label and press the same against the bottle. The second downward movement of the pressure foot 32 is idle, and will do no injury as there is no label on the shelves 29 and 30. After the label has been applied and the rollers 33 v and 34 move out of contact therewith the bottle is removed and a new bottle substituted. This action is continued as long as the machine is in operation.
